Nondisp fx of neck of third MC bone, l hand, init for opn fx

This code describes a break in the neck of the third metacarpal bone in the left hand that has not shifted out of alignment. It specifically indicates that the fracture is an open type, meaning there is a wound communicating with the fracture site, and this is the patient's first time receiving treatment for this injury.

Apply this code for a patient presenting with an open fracture of the neck of their left third metacarpal, where imaging confirms the bone fragments remain in their anatomical position. This code is appropriate for the initial encounter where definitive treatment, such as wound debridement and fracture stabilization, is being provided.

• Ensure documentation clearly specifies "nondisplaced" and "open fracture" for the neck of the third metacarpal.
• Verify laterality (left hand) is explicitly stated in the medical record.
• The "B" seventh character indicates an initial encounter for an open fracture; do not use for subsequent care.
